Description

  The present invention relates to the field of motherboards, and more particularly, to an expansion card connector and an expansion card module assembly.

  Generally, an expansion card connector (eg, M2 Socket) is usually provided at the end of the circuit board to take into account the component layout and mounting space on the current motherboard. Normally, the temperature of the expansion member is lowered by combining the heat sink, but it is difficult to fix the heat sink by making holes since there are components and wiring near the expansion card connector.

  For this reason, the heat sink of the expansion card and the heat sink of the other part are usually jointly designed in a large-area manner, but the cost is relatively high. Further, the heat sink is a heat sink that is attached to a platform controller hub (PCH) and is used in common with an element that generates relatively high thermal energy, and thus directly affects the heat radiation effect.

  Also, the large area coverage of the heat sink has reduced the component mounting space and has limited the height of the components.

  The present invention has been made in view of such a conventional problem, and provides an expansion card connector.

  The expansion card connector includes a connector body, two positioning posts, a first screw hole, and a metal shell. The connector body includes a top plane. Two positioning posts are provided on one side of the top plane. The first screw hole extends through the top plane and is located between the two positioning posts. The metal shell includes an upper plane, has two positioning holes and a second screw hole in the upper plane, the second screw hole is located between the two positioning holes, and the two positioning holes are each 2. The metal shell is fixed to the connector body by being penetrated through the positioning post of the book. The projection planes of the second screw hole and the first screw hole overlap.

  In some embodiments, the top plane and the top plane are parallel.

  In some embodiments, the area of the top plane is smaller than the top plane. Specifically, in some embodiments, the metal shell further includes an extension, the extension being bent from the front end of the top plane and extending, and abutting the top plane.

  In some embodiments, the metal shell further includes two side walls, each of which extends from both sides of the top plane and shields the connector body.

  The present invention further provides an expansion card module assembly. The expansion card module assembly is mounted on a circuit board, and the circuit board has a first protrusion and a second protrusion. The expansion card module assembly includes an expansion card connector, an expansion member, and a heat dissipation assembly. The expansion card connector includes a connector body, two positioning posts, a first screw hole, and a metal shell. The connector body includes a top plane. Two positioning posts are provided on one side of the top plane. The first screw hole extends through the top plane and is located between the two positioning posts. The metal shell includes an upper plane, has two positioning holes and a second screw hole in the upper plane, the second screw hole is located between the two positioning holes, and the two positioning holes are each 2. The metal shell is fixed to the connector body by being penetrated through the positioning post of the book. The projection planes of the second screw hole and the first screw hole overlap. The extension member is provided on the circuit board and is located between the first protrusion and the connector main body. The extension member is incorporated into the connector main body and abuts on the first protrusion. The heat dissipating assembly includes a heat sink body, a first fastening member, and a second fastening member. The first fastening member is inserted and tightened in the first screw hole and the second screw hole, and the second fastening member is tightened by the second protrusion.

  In some embodiments, the metal shell further includes two side walls, each of which extends from opposite sides of the top plane and shields the connector body.

  Specifically, in some embodiments, the connector body and the two sidewalls are welded to a circuit board.

  In some embodiments, the top surface of the expansion member is in direct contact with the heat sink body.

  In some embodiments, the metal shell further includes an extension, the extension being bent from the front end of the upper plane and extended, and abutting the top plane.

  As described in the above embodiment, by providing two positioning posts, a first screw hole, and a metal shell on the connector main body, it is not necessary to separately make a hole in the circuit board when designing the motherboard. Also, since the heat dissipating assembly can be independently incorporated with the expansion card connector, it does not require large area mounting, reduces cost, increases component mounting space on the circuit board, and increases component height. You can remove the restrictions.

FIG. 1 is an exploded view of the expansion card connector.
As shown in FIG. 1, the expansion card connector 1 includes a connector body 10, two positioning posts 15, a first screw hole 17, and a metal shell 20. The connector body 10 includes a top plane 11. Two positioning posts 15 are provided on one side of the top plane 11. The first screw hole 17 extends through the top plane 11 and is located between the two positioning posts 15.

  The metal shell 20 includes an upper plane 21, and has two positioning holes 215 and a second screw hole 217 in the upper plane 21, and the second screw hole 217 is located between the two positioning holes 215, and The metal shell 20 is fixed to the connector body 10 by piercing the positioning holes 215 through the two positioning posts 15 respectively. The projection surfaces of the second screw hole 217 and the first screw hole 17 overlap. In other words, the continuous communication between the second screw hole 217 and the first screw hole 17 forms a continuous screw hole to which the tightening device can be fastened.

  As shown in FIG. 1, the metal shell 20 further includes two side walls 23. The two side walls 23 each extend downward from both sides of the upper flat surface 21 and shield the connector body 10. The side walls 23 and the positioning posts 15 support the upper flat surface 21, and at the same time, the two side walls 23 can further exert a metal shielding effect on the connector body 10.

  Here, the upper plane 21 and the top plane 11 are substantially parallel, and there may be a slight angle shift. However, this is only an example, and the present invention is not limited to this. The upper plane 21 and the top plane 11 do not have to be parallel and may be, for example, non-parallel to each other, and the positioning holes 215 and the positioning posts 15 are interpenetrated and fixed. It is only necessary to maintain the overlap of the projection planes.

  In FIG. 1, the upper plane 21 of the metal shell 20 is located behind the top plane 11 and has an area smaller than that of the top plane 11. However, this is only an example, and the present invention is not limited to this. The metal shell 20 further includes an extension part 25, which is bent from the front end of the upper plane 21 and is extended to be able to abut the top plane 11. Thus, a metal shielding effect can be further achieved.

FIG. 2 is an exploded view of the expansion card module assembly.
As shown in FIG. 2, the expansion card module assembly 100 is mounted on a circuit board 500, where the circuit board 500 can be a computer, a motherboard of a portable electronic device. The circuit board 500 includes a first protrusion 510 and a second protrusion 520. The expansion card module assembly 100 includes an expansion card connector 1, an expansion member 2, and a heat dissipation assembly 3. The technical features of the expansion card connector 1 are substantially the same as those described in FIG.

  The extension member 2 is provided on the circuit board 500 and is located between the first protrusion 510 and the connector body 10. The expansion member 2 is energized by being incorporated with the connector body 10. Further, the expansion member 2 may include a recess for abutting on the first protrusion 510. Therefore, the expansion member 2 is prevented from sliding by being restricted by the first protrusion 510 and the connector main body 10. Here, the expansion member 2 may be a solid state drive (SSD) chip, but this is merely an example and the present invention is not limited to this.

  The heat dissipating assembly 3 includes a heat sink body 31, a first fastening member 33, and a second fastening member 35. The first fastening member 33 is inserted and tightened in the first screw hole 17 and the second screw hole 217. Since the second protrusion 520 has a screw hole, the second fastening member 35 can be tightened to the second protrusion 520. Here, the positions of the connector body 10, the first protrusion 510, and the second protrusion 520 conform to the standard specification of the motherboard standard. Therefore, the heat dissipating assembly 3 can be fixed to the expansion member 2 independently, and it is not necessary to make a separate hole on the circuit board 500 or connect to the heat sink of the PCH, thereby reducing costs and increasing heat dissipating efficiency. The effect can be achieved. Furthermore, since a part of the space on the circuit board 500 is vacant, it is possible to provide the component with higher flexibility by installing components.

  In addition, the upper surface of the expansion member 2 is brought into direct contact with the heat sink main body 31, so that a rapid heat radiation effect can be achieved. Through the fastening design of the first fastening member 33, the second fastening member 35, and the corresponding first screw hole 17, second screw hole 217, and second protrusion 520, the tightening is more ergonomic and easy to operate. Effects can be achieved.

  In some embodiments, the connector body 10 and the two side walls 23 of the metal shell 20 are welded to the circuit board 500 to provide a grounding function, further prevent signal interference, and provide a metal shielding effect. Can be increased.

In summary, the two positioning posts 15, the first screw holes 17 and the metal shells 20 are installed on the connector body 10 through the modification of the structure of the expansion card connector, so that when the motherboard is designed, it is separately attached to the circuit board 500. There is no need to fix the heat dissipating assembly 3 by making holes.
Further, the heat dissipating assembly 3 can be independently incorporated with the expansion card connector 1, does not require a large-area mounting, and can further exhibit a heat dissipating effect by being separated from a heat source of higher heat.
Further, by reducing the area of the heat dissipating assembly 3, the cost is reduced, the space for installing components on the circuit board 500 is increased, and the restriction on the height of components is released. Therefore, it is possible to provide flexibility in component layout when designing the motherboard.
